Question -

Composition of the nuclei of two atomic species X and Y are given as under

X┬а ┬а ┬а ┬а ┬а ┬а ┬а Y

Protons =┬а ┬а6┬а ┬а ┬а ┬а ┬а ┬а ┬а 6

Neutrons = 6┬а ┬а ┬а ┬а ┬а ┬а ┬а8

Give the mass numbers of X and Y. What is the relation between the two species?



Answer -

Mass number of X = Number of protons + Number of neutrons

= 6 + 6

= 12

Mass number of Y = Number of protons + Number of neutrons

= 6 + 8

= 14

These two atomic species X and Y have the same atomic number, but different mass numbers. Hence, they are isotopes.
